Sorry, not seeing how this works. The first section says:
Change where your music files are stored on Mac
By default, your music is stored here:
Home/Music/
You can change where your music files are stored.
Important: For best results, don’t change the location of the Music folder or the folders inside it.
That says not to change the location of the Music folder, which moving to external would do? Although apparently many people do put their music on an external. Even so I don't get from that how to safely copy to external, It just says "you can change where your music files are stored."
The next step says:
Change where imported files are stored
- In the Music app
on your Mac, choose Music > Preferences, then click Files. - Click Change, then select a new location for your files.
- From now on, new songs and other items you import are stored in the new location. Songs you’ve already imported stay in their current location.
That just creates an empty folder on the external called "Automatically Add to Music," which I guess means that's where new ripped or purchased files go?
The Music folder itself has a subfolder called Music and a 74MB file called Music Library. But there is still a folder called iTunes(???). I assume Music Library *points to* iTune/iTunes Music/ which contains many folders full of the song files in my collection?
I also have a couple of folders of downloaded high-res music that Music app/iTunes can't play, but they are in the main Music folder and I'd want them to go with the whole Users/Music conglomeration to the external since they use a bunch of space too. That's why I'm trying to do this a "safe," "careful," way ...
